Sheila Nevins, HBO's president of documentaries, said "probably 160 lawyers" worked with them on the film to avoid litigation from the Church of Scientology.
Many film critics who reviewed the documentary quickly received emails from the Church of Scientology asking for "their side of the story" to be included in reviews of the film and warning them "not to be the mouthpiece for Alex Gibney's propaganda."
Alex Gibney captured the footage of the Church of Scientology's headquarters by using an aerial drone.
Short-listed for 'Best Documentary' (last 15 films) at the 88th Academy Awards 2016.
Scientology has two major landmark buildings in the Hollywood area, both of which appear in the film's cut-away footage. The Scientology Celebrity Center is located on Franklin Ave, near the bottom of the Hollywood Hills. It is the castle/mansion-like building seen in this film when first discussing John Travolta. The more iconic baby blue building photographed by drone and shown much more frequently in the film is the primary church and office headquarters of Los Angeles. It is located at 4810 Sunset Blvd.
